On page 88 of Will Tirion's The Cambridge Star Atlas, Fourth Addition you will find a Table list of stars with exoplanets providing data including RA and Dec. For the same data on stars with exoplanets discovered after the Atlas printing he recommends the website of the Planetary Society:

Kepler 66 is a 15.3v magnitude G star . From a truly dark sky and a great instrument an 8" might show it while a 10" would be more realistic in a country setting . Kepler 67 is substantially more difficult at 16.2v but is also a G star. Good luck.
